Abstract:


Objective: The present study had determine the impact of prolonged storage in a cartridge or syringe on the quality of the [18F]-radiopharmaceuticals used in our center [18F]fludeoxyglucose and [18F]fluorocholine). [18F]-radiopharmaceuticals registered as ready-to-use drugs are prepared in multidose flasks. When the change of packaging must be made extemporaneously for the preparation of patient unit doses in a syringe or cartridge, this is under the responsibility of radiopharmacists. As drug quality in medical devices (syringe or cartridge) is not evaluated during the marketing authorization of such radiopharmaceuticals, an evaluation of drug stability in such devices seems interesting. In addition, if there are difficulties in patient care (placement of the catheter, lack of personal, etc.) or equipment problems (technical issue with the automated dispenser delaying the delivery of the prepared dose), the contact time of [18F]-radiopharmaceuticals with the medical devices (cartridge or syringe) increases.

Methods: Appearance, pH, radiochemical purity, sterility and endotoxin tests were made according the current European Pharmacopoeia. Adsorption tests were made according the literature.

Results: There was no drug absorption of [18F]fludeoxyglucose or [18F]fluorocholine after 1.5h, which may be related to their hydrophilic nature. No drug radiolysis was observed even after dilution of the radiopharmaceuticals (appearance, pH, and radiochemical purity were unchanged). No impurity from medical devices (cartridge or syringe) was observed, and microbiological aspects remained in specification of the current European Pharmacopoeia.

Conclusion: These radiopharmaceuticals repackaged in plastic medical devices retained their quality after dispensing and prolonged storage.
